1 Application filed October 10, 1902. Serial No. 126,671. (No model.)

Jrermany, have invented new and useful im provements in apparatus forcontinuously operating spinning-machines for arresting slots, of whichthe following is a full, clear, and exact specification.

The object of the present invention is an ap parat-us for continuouslyoperating spinningmachines for arresting thick parts of the thread ortwist, which device is applicable for all thicknesses (numbers) of thethread or yarn and makes use of the well-known arrangement ofguide-slots. The device is, however, new, inasmuch as the saidthreadguide slots, tapering to the rear, are placed upon an adjustably-arranged cross-plate provided alternately with elevations anddepressions, 011 the crests of which elevations saidslots are arrangedso that this slotted plate when adjusted to the required diameter of thethread will not only arrest any sidewardly-projecting fibers, but willalso break off the thread at any knots or thickness at the slots, andwill, moreover, collect the broken thread ends which continue to bedelivered in its depressions, so that these ends do not fall down uponthe spindles or become tangled and spun together with the other threadsor yarn.

It is essential that the slotted plate should be properly adjusted forthe thickness of the delivered threads of the spinning-machine and,namely, so that the threads in their passage through the slots remaincontinuously in contact with the edges thereof without actually rubbingon them.

In the accompanying drawings, Figure 1 shows in side elevation the frontpart of the spinning-machine, which is provided with the invention andof which the parts connected with the said invention are illustratedmore or less diagrammatically. Figs. 2, 3, and L illustrate in plan,front view, and cross section the slotted plate forming the essentialpart of this invention.

Referring first to Fig. 1, a a indicate the thread-delivery rollers ofthe spinningmachine, from which the threads passing through the usualeyes I) pass to the spindles.

(Not shown in the drawings.) Between the rollers a and the eyes I) thedevice of the present invention is inserted. This consists, essentially,of the metal plate 0, placed transversely to'the direction of thethreads and formed in this instance of corrugated tinplate, Fig. 2,reinforced behind by means of a bar (Z and supported by the bracketsefrom the shaft f.

I11 consequence of its corrugation the crossplate 0 possessesalternateelevations and depressions. At the crest of each of theseelevations and along thesame is arranged a slot which is open to thefront and graduallycontracted to the rear, Fig. 3. These slots serve asguides for the threads delivered from the rollers a. The front edge ofthe slotted plate 0 is preferably provided with an edging of plush gwhich is secured firmly thereon by means of a row of holes h and isdesigned to collect the fibers which accumulate in the depressions ofthe plate a and prevent them from falling down upon the spindles.

The slotted plate 0 can be adjusted according to the requirements byturning the shaft f. This is requisite in order to admit of the passageof threads of various strength or fineness, and this while retaining theloose contact of the threads with the edges of the slots. If the slottedplate c is adjusted for a given size or number of thread and thereoccurs in the thread a flaw, such as a knot or a thickening, and thisreaches the respective slot of the plate, the knot is arrested, thethread breaks, and the continuously-delivered thread passing from therollers a collects in a collecting-depression of the plate 0. It cannot,therefore, fall down upon the spindles or be tangled with any otherthread. 011 the other hand, if the loose filaments projecting sidewisearrive on the passage of the thread through the slot 9, on the edges ofwhich they have a slight contact in consequence of the adjustment, theywill also be stopped and be collected in the depressions, so that thethread is at the same time cleaned to a certain extent.

In the machine illustrated the guide-eyes b, Fig. 1, are movablevertically, being placed 011 a bar 1', which can be moved verticallyingrooves upon the machine-frame for the purshaft Z, revoluble by hand.

p0se,well known, of regulating the swelling of the threads. The said bar2 is supported upon two lever-arms 7c, which are placed upon the Thisshaft bears at determined regular intervals the arms m, which by thelinks it are compulsorily connected with arms 0 upon the shaft f of theslotted plate 0. A slot-anchpivot connection 19 z admits in thewell-known manner of the adjustment of the working length of the links01. Further, the shaftlcarries a ratchet-wheel 7*, into which the catch8 engages. In this case the adjustment of the slotted plate 0 to adjustthe width of its guide-slots to the fineness of the delivered thread iseffected after loosening the slot-and-pivot connection 19 z. Thisconnection is tightened again when the plate 0 has thus been adjusted,whereby the guideeyes b occupy their lowest position. Themachine beingset into operation when the guideeyes I) are raised by rotating theshaft Z, carrying the lever-arms 7c, the slotted plate 0 by the agencyof thelevers m n 0 sinks from its adjusted upper position (indicated indotted lines) to that shown in f nll lines, so that during this motionof the guides Z) the delivered threads are guided always atsubstantially the same slot width, although they are some what pushedaway from the shaft f when the guide-eyes Z) move upward.

If the thread guide eyes I) are fixed im- 1novab1y,the above-describedconnection with the slotted plate 0 becomes, of course, unnecessary.

What I claim is' 1. In a continuously-operating spinning machine anapparatus for arresting thicknesses of the delivered threads, consistingof an adjustable cross-plate formed with alternate elevations anddepressions and rearwardly-tapering thread -guide slots on the crests ofthese elevations, the adjustment of said plate allowing the width of theguideslots to be adjusted to the number (fineness) of the deliveredthread for arresting thick parts thereof and formed to catch in itsdepressions the broken threads which continue to be delivered by thespinning-machine, substantially as set forth.

2. In a continuously-operating spinningmachine, vertically-movablethread-guide eyes, an adjustable cross-plate formed with alternateelevations and depressions and rearwardly-tapering threadguide slots onthe crests of these elevations for the purpose described and connectingmeans between said eyes and cross-plate arranged so as to automaticallymove this latter relatively to the movement ofthe threadguide eyesandtohave always the threads guided at substantially the same slotwidth, as described.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
